TPS62172QDSGRQ1 TI DC DC Switching Regulators

The TPS62172QDSGRQ1 is an AEC‑Q100 qualified synchronous step‑down (buck) DC‑DC converter from Texas Instruments, delivering a fixed 3.3 V output at up to 500 mA . It operates from a 3 V to 17 V input range, making it suitable for 12‑V intermediate supply rails and battery‑powered systems . The device features a 2.25 MHz switching frequency, enabling small inductor sizes and fast transient response via the DCS‑Control™ topology . A 17‑µA typical quiescent current supports high efficiency across light loads, with seamless power‑save mode transition . Additional features include power‑good output, 100% duty cycle mode, short‑circuit protection, and thermal shutdown . The compact 2 mm × 2 mm WSON‑8 package (TSSOP‑8 exposed pad) makes it suitable for space‑constrained applications . Operating junction temperature range is –40 °C to +125 °C . Ideal applications include automotive infotainment systems, instrumentation clusters, LED lighting, industrial automation, battery‑operated equipment, and portable devices requiring a space‑efficient, high‑efficiency power solution .
